ROY A. PIERCE, OF KANE, PENNSYLVANIA.

POOIPBALL FRAME.

Specification of Letters Patent.

Patented March 23, 1909.

Application led May 7, 1908. Serial No. 431,377.

To all 'whom it may concern:

Be it known that I, ROY A. Pinnen, a citizen of the United States,residingI at Kane, in the county oi'- McKean and State of Pennsylvania,have invented certain new and usolul Improvements in Pool-Ball Frames,and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the saine.

This invention relates to that class of devices consisting of anequilatoral triangular shaped frame used in bunching or setting up thepool balls in pyramidal form upon a pool or billiard table.

The principal object of the invention is to produce a frame oi this kindby means of which the balls may be placed in close. contact with eachother and which is adapted to be enlarged prior to its removal fromaround the balls to enable the same to be lifte l from the table withoutdisturbing the balls.

l/Vith this and other objects in view, the invention consists of certainnovel jfeatures of construction, combination and arrangement of parts,as will be more vfully described and particularly pointed out in theappended claims.

In the accompanying drawings, Figure 1 is a plan View of the rack withthe cross piece pressed u on the rear row oi" balls and with parts broren away; Fig. 2 is a similar view, the rear cross piece in normalposition. liig. 3 is a longitudinal section on line 3"-3 of Fig. 2.

In the accompanying drawings, the numerals l1 and 2 represent the twoside rails or pieces of an equilateral triangular shaped pool ballframe, which pieces may be separated and afterward connected together atthe apex of the angle formed thereby, or the two pieces may beconstructed from a single piece of material of the required length bentto form the side pieces of the frame.

It is to be understood of course that I do not Wish to be confined in myinvention to the material used in the construction thereof.

In carrying out the invention the cross bar 3 is separate anddisconnected from the side pieces 1 and 2 and is provided at its innerface and at opposite ends with inwardly ex tending guide pins 4 whichextend in corresponding longitudinally extending sockets 5 produced orformed in the rear or disconnected ends oi' the side pieces. Coilsprings G are litted in the sockets to normally exert pressure upon theguide pin and by this means the cross piece is normally held in spacedrelation with the disconnected ends of the side pieces, as clearly shownin Fig. 2. The rear or disconnected ends of the side pieces terminate inenlarged portions the outer faces of which extend in parallel planeswith the guide pins and are preferably l'lush with the ends of the crosspiece. Flat keeper plates 7 of spring metal, or other materialpossessing sul'licient resiliency, are attached to the outer laces ofsaid plates extending a suitable distance beyond the rear ends of theside pieces and terininatiing` in inwardly and laterally extendingportions S which constitute stops to limit the movement of the crosspiece in one direction, as will be obvious. In bunching the balls uponthe table they are placed. in the lramc and the rear cross piece ispressed imvardly against the tension of the pressure s )ring 7 andagainst the rear row olf balls to place the several balls in closecontact with each other. This having been accomplished the pressureexerted upon the cross piece by the operator is released to permit thecross piece to spring outwardly into its normal position to increase thesize ol the frame in order to permit it to be removed lrom around theballs and from the table without disturbing the former.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without roquiring a more extendedexplanation.

Various changes in the lorm, proportion and the minor details ofconstruction may be resorted to without departing from the prin.- oipleor sacrificing any oi the advantages ol the invention, as deiined in theappended claims.

I-Iaving thus described my invention what I claim as new is 1- l. A poolball frame comprising two rigid side pieces, a third side piececonsisting of a movable presser bar adapted to force the pool balls inclose contact with each other, and resilient means lor normally holdingthe movable presser bar in spaced relation with the ends of the rigidside pieces.

2. A pool ball frame comprising two rigid side pieces 'formed withlongitudinal sockets in their outer or disconnected ends, a third sidepiece consisting ol: a movable presser bar formed with inwardlyextending guide pins plates attached to said ends of the rigid side tofit in said sockets, pressure springs in said l pieces and provided withinwardly extendsookets to normally hold the movable presser bar inspaced relation with the outer ends of ing portions whioh limit theoutward movethe rigid side pieoes, and means for limiting I ment of themovable sidepiece.

the outward movement of the former. i In testimony whereof l havehereunto set 3. A pool ball frame comprising two rigid l my hand inpresence of two subscribing' side pieces7 a third side piece consistingof a l witnesses.
